booger?

We have a dishwasher who doesn't know english very well -- he's Middle Eastern or something. So at the end of our shifts today, one of the waitresses was rubbing her nose and sniffling.
Dishwasher: "Are you okay?"
Girl: "Yea, I just had a booger."
Dishwasher: "A what?"
Girl: "A booger. Want me to show you?"
Everyone: *cracks up*

hehe, poor guy. we love him though.
